Application led April To all whom t may concern:

lie it lrnoivn that l, CHARLES MYRON Jeans, a citizen of the United States, residing at North Yakima, in the county of Yakima and State of lvl/vashington, have in vented certain new and useful Improvements in 'VVrenchesg and l do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in Wrenches, particularly that type adapted for use in removing` grease cup caps.

'if he primary object is to provide a simple and improved device of this character which will be especially valuable in removing caps from grease cups so positioned that the operator cannot reach them Without the aid of a tool.

Another object is to provide a simply constructed and highly efficient device of this character which may be easily operated and will eliminate the necessity of having soil-ed hands after refilling grease cups.

ll! ith these and other objects in view, m invention resides in certain novel features of construccion, and in the combination and arrangement of parts as will be more fully described and claimed, the descriptive matter being supplemented by the accompanying' drawing in which L'Fig'ure l is a sido elevation of the Wrench applied to a grease cup cap, and

Figs. 2, 3 and il are sectional views taken on the lines 2-2, 3 3, and 4.4i of Fig. l in the directions indicated by the arrows.

is clearly illustrated in the accompanyingl drawing, my device includes a handle l nfhich is preferably cylindrical in shape and is formed from any suitable material, said handle having' its surface imurled.

i ilurality of east springl arms extend from one end of the handle l, each of said arms having' one end secured in the handle hv any,r suitable means, preferably cast with the handle which is solid. The outer free ends of the arms 2 are beveled outwardly for a. purpose to be fully set forth in the following description.

For the purpose of providing means for gripping the flange It of the cap C of agrease c p G to remove said cap each arm 2 1s provided on its inner face With a longitudinally extending recess 4, each of which is formed by oppcsitely lieveling the arm at points ad- Speccaton of Letters Patent.

jacent the beveled. ends 3, the bevels 5 converging toward the longitudinal aXis of the implement. rlhe bevels 5 are slightly concave so as to give the recess a hook 6 to enthe flange R and retain it in its proper position for removing the cap.

TWhen usinp` this cap remover the operator grasps the handle l and forces the beveled ends 3 to slide over the rim R of the cap to be removed. Upon completion of this operation the hooks G are securely holding the cap from pulling,` free from the arms and the recesses 4 are engaged With the serrations on the flange so as to prevent the arms from slipping` Without removingl the cap.

The resiliency of the arms 2 is materially increased by cutting` away a portion of the metal on their inner faces at points near the handle l. ln cutting out the above named portion the arms are eut transversely from their inner faces to a point approximately one-half` the diameter and then cut away longitudinally, gradually tapering to the inner faces of said arms to points substan tially midway their lengths. By increasing the resiliency in this manner, the degree of spreading is increased, so that various sized ca] s may be removed with the same Wrench.

ln order to assure positive engagement of the teeth and cap flange, l have provided a ring which is adapted to slide over the arms 2 and contract the free ends around the can. The inner periphery of the ring is oppo tely beveled to form a continuous V- shapes rib 8 adapted to engage sei-rations 9 on the outer faces of the arms The pressure of the biting; teeth a on the ilange R may be varied by adjusting the ring in the serra-tions.

Although l have described the ring` 7 as haring' a la -shaped rib 8 to engage the serrations, l Wish it understood that I may eliminate the rib and use a plain ring.

From the foregoing description, taken in connection with the aecompanyingdrawes, the construction and operation of the invention Will be readily understood Without redini-inf; a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without departingfrom the principle or sacrilicinfg,Y any of the advantages of the claimed invention.

l claim:

l, A grease cup cap remover comprising a hand grip, a plurality of diverging arms on said hand grip, movable toward and from the longitudinal axis of the implement, each of said arms being provided with a longitudinally extending outwardly beveled face at its end to guide the ends of the implement over a cap, and each of said arms being provided with 'a pair of concave recesses converging toward the longitudinal axis of the implement to form '-'a longitudinally ex tending biting tooth, said tooth being curved longitudinally and adapted to receive the flange on the grease cupy cap.

2. A grease cup cap remover Comprising a hand grip, a plurality of diverging resilient arms extending from one end of said hand grip, said arms having portions out away from their inner faces at points near the hand grip to give them increased resiliency, each of said arms being provided with a longitudinally extending outwardly beveled face at its end to guide the ends of the implement over a cap, each of said arms being provided with a pair of concave recesses converging toward the longitudinal axis of the implement to form a longitudinally extending biting tooth, said tooth being curved longitudinally and adapted to receive the flange, of a grease cup oap, said arms being serrated on their outer faces, and a ring slidable over said arms and having its inner periphery oppositely beveled to forni a continuons V-shaped rim to engage the serrations and hold the arms contracted upon the cap flange.

ln testimony whereof l have hereunto set my hand.

CHARLES MYRO'N J CNES.
